Which identifies the main purpose of biological taxonomy? classify organisms by using common names for easy identification of species by scientists create phylogenetic trees that organize species based only on physical characteristics use a systematic method to name, organize, and show relationships among species create common names that can be applied to multiple organisms found in different regions.

The main purpose of biological taxonomy is to use a systematic method to name, organize, and show relationships among species. Scientists name, describe and classify organisms ranging from insects, animals, plants to microorganisms by using behavioral, genetic and biochemical observations.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
